A fake Blancpain 5200 is a replica of the Blancpain Fifty Fathoms Bathyscaphe Chronograph Flyback, reference 5200. The term covers a wide range, from cheap quartz lookalikes to high-end "super clone" builds with decorated automatic movements. Telling them apart comes down to four things: the movement inside, the finishing on the case and bezel, the printing and alignment on the dial, and how the chronograph pushers and crown actually feel in use.
What the term covers
Buyers searching for a fake Blancpain 5200 usually land in one of three tiers, and each behaves differently once it is on the wrist:
- Budget replicas. Quartz or low-grade automatic movements, mineral glass, printed dial text that sits slightly off center, and a bezel that turns with a hollow click.
- Mid-tier automatics. A generic automatic chronograph movement, sapphire crystal, and closer case proportions, but with a rotor and bridges that look nothing like the genuine caliber.
- Super clone builds. A decorated automatic movement made to resemble the in-house calibre, correct case dimensions, and ceramic bezel inserts. These are the ones that get mistaken for the real thing in photos.
None of these are made by Blancpain. The reference number, the branding, and the packaging are all copied, which is what makes them a legal and ethical problem rather than just a cheap alternative.
How to tell a fake 5200 from the real one
Work through these checks in order. The first one you fail usually settles the question.
- Movement. The genuine ref 5200 runs Blancpain's in-house flyback chronograph caliber, a high-beat automatic with a column wheel and flyback function. A replica will have a generic chronograph module, often with a pusher layout that does not match the real one.
- Chronograph feel. Press the pushers on a genuine piece. The start, stop, and flyback actions are crisp and short. Replicas feel mushy, grind, or need a hard push.
- Case finishing. Look at the transition between brushed and polished surfaces. Genuine Bathyscaphe cases have sharp, consistent lines. Replicas show soft edges and uneven brush grain.
- Dial printing. Text should be crisp, evenly spaced, and level. On fakes, the logo sits slightly high or low, and lume plots vary in thickness.
- Bezel action. A genuine dive bezel indexes cleanly with no play. Replica bezels wobble or skip past a marker.
- Water resistance. The real 5200 carries a 300 m rating. Most replicas are not tested to any rating at all, even when the caseback is engraved with one.
Movement differences in plain terms
The genuine caliber and a replica movement are not close cousins. Blancpain builds the real movement in-house, finishes it by hand, and regulates it to chronometer-adjacent tolerances before it leaves the factory. A replica uses a mass-produced chronograph base with a decorative plate screwed on top. That plate often carries fake jewel count engravings and a rotor that copies the brand's lettering, which is why sellers photograph the caseback from an angle or leave it out of the listing entirely.
Practical consequences show up fast. Replica movements lose or gain time unevenly, the chronograph seconds hand stutters or resets past zero, and the power reserve is shorter and less predictable.
Case, bezel, and dial details worth comparing
The Bathyscaphe chronograph has a roughly 43.6 mm case, a ceramic bezel insert with a liquidmetal-style scale on the genuine version, and a sapphire crystal with an anti-reflective coating on both sides. Replicas frequently get the case diameter close but miss the thickness, which changes how the watch sits. The crystal coating is another tell: fakes usually have no inner coating, so the dial washes out under bright light instead of staying legible.
Why replicas fall short over time
- Gaskets are low grade, so moisture gets in during swimming or even hand washing.
- Lume is weak and fades within minutes rather than hours.
- Bracelet and strap hardware stretches, and spring bars are a common failure point.
- Service is difficult, since no authorized watchmaker will touch a counterfeit piece.
- Resale value is close to zero, so the money is gone the day it arrives.
Buying a genuine 5200 on the secondary market
If your goal is the real watch, buy the seller as much as the watch. Ask for the reference and serial, a clear photo of the caseback and movement, the original box and papers, and a service history. A short video of the chronograph running and resetting is worth more than a dozen still photos. Have an independent watchmaker open the case before money changes hands, and use a payment method with buyer protection.
Quick answers
Is a fake Blancpain 5200 waterproof?
Treat it as splash resistant at best. The engraved depth rating on a replica reflects the real watch, not the copy.
Can a jeweler tell a fake 5200 from a real one?
Yes, and usually in under a minute. Opening the case and looking at the movement is the fastest route.
Are super clone 5200s worth buying?
They cost a fraction of the genuine watch, but they stay counterfeits. They cannot be serviced by the brand, hold no value, and carry legal risk at import and resale.
What should I look at first on a used 5200?
The movement and the caseback engraving, then the dial printing and bezel action. Those four checks catch most fakes.
